Dragonfly (Odonata) Species Diversity in the Sigolo-Golo Tourism Area, Jombang, East Java
Summary
Researchers assessed dragonfly species composition and diversity in the Sigolo-Golo tourism area of East Java, Indonesia using the Visual Encounter Survey method, identifying 12 species from five families across three sampling locations in a secondary forest habitat.
The sigolo-golo area is a tourist area with waterfalls and rivers. It is located in a secondary forest far enough from settlements, so it has the potential to be a habitat for dragonfly diversity. This study aims to analyze the composition and diversity of dragonflies in the Sigolo-golo tourist area. Data collection was carried out using the Visual Encounter Survey (VES) method. The results of research conducted in three locations showed that there were 12 species from five families, namely Libellulidae, Euphaeidae, Calopterygidae, Chlorocyphidae, and Platicnemididae, with a total of 319 individuals. The species with the highest relative abundance value in this study was Pantala flavescens with a value of 77.40%. The value of species diversity at this location is H' = 0.984, which indicates that the diversity index value is low.ABSTRAK: Kawasan Sigolo-golo merupakan area wisata dengan terdapat air terjun dan sungai, yang terletak di dalam hutan sekunder yang cukup jauh dari pemukiman, sehingga berpotensi sebagai habitat bagi keanekaragaman capung. Penelitian ini bertujuan untuk menganalisis komposisi, dan keanekaragaman capung di kawasan wisata Sigolo-golo. Pengumpulan data dilakukan dengan menggunakan metode Visual Encounter Survey (VES). Hasil penelitian yang dilakukan di tiga lokasi menunjukkan bahwa terdapat 12 spesies dari lima famili, yaitu Libellulidae, Euphaeidae, Calopterygidae, Chlorocyphidae, Platicnemididae dengan total 319 individu. Nilai kelimpahan relatif yang tinggi pada penelitian ini yaitu Pantala flavescens dengan nilai sebesar 77.40%. Nilai keanekaragaman jenis pada lokasi ini adalah H' = 0.984, yang menunjukkan bahwa nilai indeks keanekaragaman tergolong rendah.

Response of Odonata assemblages to disturbance in urban freshwater habitats
This paper is not about microplastics — it investigates how Odonata (dragonfly and damselfly) assemblages respond to different levels of habitat disturbance caused by urbanization in freshwater habitats in Ghana.
Community Structure of Benthic Macroinvertebrates as Bioindicators of Water Quality in the Upstream Setail River, Banyuwangi, East Java, Indonesia
Researchers assessed the community structure of benthic macroinvertebrates as bioindicators of water quality in the upstream reach of the Setail River in Banyuwangi, East Java, Indonesia, which has experienced declining water quality due to surrounding human activities. The study used macroinvertebrate assemblage composition and diversity indices to characterize ecological status and identify pollution pressure along the river corridor.
Occurrence of microplastics in edible aquatic insect Pantala sp. (Odonata: Libellulidae) from rice fields
Researchers detected microplastics in edible dragonfly larvae collected from rice fields, finding an average of 1.34 particles per individual with fragments being the most common type, raising concerns about microplastic transfer through insect-based food chains.
Bird population and bird hunting in the rural ecosystem of Cijambu, Sumedang, West Java, Indonesia
Researchers investigated bird species diversity and population dynamics across natural forest, coffee agroforestry, vegetable garden, and homegarden habitats in Cijambu, West Java, Indonesia, using point count surveys and interviews with hunters. They found that habitat type strongly influenced bird community composition, and that illegal hunting, forest degradation, and pesticide use were significant pressures reducing bird diversity in these rural ecosystems.
